When updating an existing taxonomy term that shares its `term_id` with
another term, we generate a new row in `wp_terms` and associate the updated
term_taxonomy_id with the new term. This separates the terms, such that
updating the name of one term does not change the name of any others.
In cases where a plugin or theme stores term IDs in the database, term splitting
can cause backward compatibility issues. The current changeset introduces
two utilities to aid developers with the transition. The `'split_shared_term'`
action fires when the split takes place, and should be used to catch changes in
term_id. In cases where `'split_shared_term'` cannot be used, the
`wp_get_split_term()` function gives developers access to data about terms
that have previously been split. Documentation for these functions, with
examples, can be found in the Plugin Developer Handbook. WordPress itself
stores term IDs in this way in two places; `_wp_check_split_default_terms()`
and `_wp_check_split_terms_in_menus()` are hooked to `'split_shared_term'` to
perform the necessary cleanup.
See [30241] for a previous attempt at the split. It was reverted in [30585]
for 4.1.0.

This is a revert of [30494], [30492], [30347], and [30334]. The latter
changeset was a revert of [30336], which was a revert of [30241].
Watch for Term Splitting, Version III in version 4.2, coming soon to a
WordPress trunk near you.

* If the split term ID is stored as 'default_category', 'default_link_category', or 'default_email_category', update it to the new ID.
* If the split term ID is associated with a nav menu item, update that piece of postmeta to the new ID.

* Check if the host is considered a safe redirect host.
* Check if the host is another domain in a multisite installation.
* Add a filter to control this.
This only occurs when the DNS resolution of a domain points elsewhere in an internal network, but only internally (and has its own public IP outside the network). This could be considered a bad configuration.

The spamming of a site no longer directly affects a user of said site.
Moves the spam check to the wp_authenticate filter. Networks in need
of enhanced spam-fighting should leverage this same technique.
Allow is_user_spammy() to accept a WP_User object.

In core UI (and XML-RPC), we first create an auto-draft via get_default_post_to_edit(), which means the first "save" is in practice the first revision.

* Add a post ID argument to the_content(), get_the_content(), the_remaining_content(), and get_the_remaining_content().
* Pass the post ID to the the_content filter.
* Remove the format_pages global.
* Declare format_content and split_content as vars in WP_Post.
* phpdoc for the the_content filter that documents the new ID argument and denotes it as not-so-portable.

* Uses post_name of revisions to store a post version number (-v1), so we know what has been fixed.

* Currently handles link, quote, image, gallery, audio, and video formats.
* `add_theme_support()` for a given post format is now an indicator that the theme handles format-specific metadata.
* If no support for a given format is defined, fallback output will be generated and hooked onto the_content if a post has metadata for that format.
* Fallbacks attempt to be smart about not duplicating data already appearing in the post content itself. Gallery is particularly liberal, looking for any instance of the gallery shortcode in the content, not just an exact match to the gallery shortcode defined in the format-specific meta.
* Compat output defaults to being wrapped in a `div` with a class of `post-format-content`.
Theme authors: please test and evaluate, keeping in mind that the goal is to support user expectations of not losing format-specific data they've entered in the admin when viewing the front-end of their site.

The exceptions to this are update_post_meta() and add_post_meta() which are often used by plugins in POST handlers and will continue accepting slashed data for now.
Introduce wp_upate_post_meta() and wp_add_post_meta() as unslashed alternatives to update_post_meta() and add_post_meta(). These functions could become methods in WP_Post so don't use them too heavily yet.
Remove all escape() calls from wp_xmlrpc_server. Now that core expects unslashed data this is no longer needed.
Remove addslashes(), addslashes_gpc(), add_magic_quotes() calls on data being prepared for handoff to core functions that until now expected slashed data. Adding slashes in no longer necessary.
Introduce wp_unslash() and use to it remove slashes from GPCS data before using it in core API. Almost every instance of stripslashes() in core should now be wp_unslash(). In the future (a release or three) when GPCS is no longer slashed, wp_unslash() will stop stripping slashes and simply return what is passed. At this point wp_unslash() calls can be removed from core.
Introduce wp_slash() for slashing GPCS data. This will also turn into a noop once GPCS is no longer slashed. wp_slash() should almost never be used. It is mainly of use in unit tests.
Plugins should use wp_unslash() on data being passed to core API.
Plugins should no longer slash data being passed to core. So when you get_post() and then wp_insert_post() the post data from get_post() no longer needs addslashes(). Most plugins were not bothering with this. They will magically start doing the right thing. Unfortunately, those few souls who did it properly will now have to avoid calling addslashes() for 3.6 and newer.
Use wp_kses_post() and wp_kses_data(), which expect unslashed data, instead of wp_filter_post_kses() and wp_filter_kses(), which expect slashed data. Filters are no longer passed slashed data.
Remove many no longer necessary calls to $wpdb->escape() and esc_sql().
In wp_get_referer() and wp_get_original_referer(), return unslashed data.
Remove old stripslashes() calls from WP_Widget::update() handlers. These haven't been necessary since WP_Widget.
Switch several queries over to prepare().
Expect something to break.

Remove the UI for setting the default width and height for embeds. Width was confusing as it
was blank by default (inheriting the content width from the theme, or 500px). The height is
now calculated as 1.5x the content width, or 1000px, whichever is smaller.
The [embed] shortcode can still receive manual height and width attributes. This just removes
the global settings.
